INTRODUCTION AND OBJECTIVES: The origin of emboli involved in patent foramen ovale (PFO)-related ischemic events remains poorly documented. Our objective was to evaluate venous thromboembolic (VTE) disease as a potential source of PFO-related embolic events.
METHODS: Patients scheduled for PFO closure for secondary prevention of PFO-related arterial embolic events underwent a systematic VTE risk evaluation. This included: a) a detailed questionnaire on past VTE history to identify clinical situations associated with a high risk of VTE at the time of the embolic event, and b) abdominopelvic magnetic resonance imaging (MRI) with venography to identify abdominal or pelvic venous disease.
RESULTS: From July 2020 to May 2023, 366 consecutive patients (median age 51 [range, 42-58] years; 42.9% female) were prospectively included. A prior VTE event, a high-risk VTE situation, a hyperthrombotic state, or an abdominal or pelvic venous anomaly on MRI were present in 8.5% (95%CI, 6.0-11.8), 22.7% (95%CI, 18.7-27.2), 7.1% (95%CI, 4.9-10.2), and 36.3% (95%CI, 31.6-41.4) of patients, respectively. Overall, 58.5% (95%CI, 53.4-63.4) of patients had at least 1 of these conditions. MRI identified several previously undiagnosed pelvic venous anomalies, including pelvic varices in 20.0%, May-Thurner/Cockett in 9.8%, and nutcracker syndrome in 7.4%. Imaging abnormalities were more frequent among younger patients (aOR, 1.02; 95%CI, 1.00-1.04) and women (aOR, 1.94; 95%CI, 1.25-3.02).
CONCLUSIONS: A prior VTE event, a high-risk VTE situation, a hyperthrombotic state, or an abdominal or pelvic venous anomaly may be present in most patients with a history of a PFO-related arterial event.
